Attic ventilation is basically the flow of air through your attic. Your ventilation components (type) must provide for the adequate inflow of cooler outside air (soffit vent), and adequate outflow of your hotter attic air (turbine vent illustrated).
Ventilation of the home attic is important for two reasons.
Thus, temperature (high utility bills) and moisture control are the major reasons for providing attic ventilation.
An attic ventilation system is a fundamental requirement for attic ventilation, and provides for natural wind/air cross ventilation of your roof.
Soffit vents are screened intake openings (vents) along the underside of the eaves of the home. This vent provides for the inflow of air.
ATTIC VENT: OUTFLOW (ROOF VENT) There are several types of outflow vents that can be utilized. Selection of an outflow vent is based on how energy efficient you want your home to be. See the options below.
Wind turbines use the natural force of the wind to create air flow and provide ventilation. The free spinning turbine is self-lubricating, drawing hot humid air out from the attic. Turbines come in two sizes: 12" and 14". The latter provides almost 30 percent more air flow.
Power attic ventilators work better than a standard vent, and wind turbine ventilator systems. They are electrically powered fans installed in the roof and are controlled by a thermostat which insures your attic ventilation process. They will work even in the absence of natural outdoor wind/breeze.
The best option by far is the Super Cyclone Solar Powered Ventilator. Using natural resource power, this unit will significantly increase the hot air outflow, which in turn, will result in lower monthly cooling costs. Other benefits of solar powered ventilators, is they do not use energy (no wires) and will add additional years of life to your roofing materials and other parts of your home.
Please note that while we provide information and recommendations on attic ventilators, we do not provide or install roof ventilators (i.e. wind turbines, powered ventilators, or solar powered ventilators). Please contact your roofing contractor for installation and pricing information on these items.
